I know I am easier on the brakes in my RV than in my daily driver. The RV and toad weigh about 5 times as much as my little truck so my foot comes off the gas a lot quicker and more frequently rolling resistance comes into play. Add the tow haul downshifting and the open road nature of RVing and there are times when I go 100s of miles without touching the brakes. So it is not surprising that brakes wear is minimal.
